Looking into doing work on some Jet Pumps to adjust the clearance back to spec on the Impeller but I'm not noticing any shims listed on Yamaha's parts diagram lookup for the newer year skis. on vx skis I'm seeing listed 2 oil seals sitting on the impeller shaft just below the impeller however the fx skis have a spacer right below the impeller before the 2 oil seals.... is that the shim spacer to adjust clearance? is it even possible to adjust the clearance on the fx impeller?
